Abstract

The utility model relates to a graded cascading hydro-power generating unit, which comprises a water turbine, a casing and a power generator. A water-through casing of the impulse water turbine of each power generating unit is a pipeline or a pipeline with a water turbine cavity inside; connecting flanges are arranged at two ends of the pipeline; the water turbine is arranged inside the pipeline or the water turbine cavity; a water outlet of the water turbine cavity is directly communicated with a water outlet pipeline or smoothly connected with the water outlet pipeline in a curved manner; and the power generating units can be mutually cascaded or independently connected with a graded power station dam of a river channel. As the water-through casing of the impulse water turbine of each power generating unit is arranged into the pipeline, the graded cascading hydro-power generating unit is more convenient in processing and installation and facilitates maintenance. As the flanges are arranged at the two ends of the pipeline, cascading or dam building connection is convenient and rapid. As the power generating units can be cascaded, potential energy of water can still function in a next step when the water passes through a previous water turbine pipeline, and the graded cascading hydro-power generating unit more sufficiently uses hydroelectric resources and has the advantages of simple structure, low cost and convenience for installation and construction.

Description

The Hydropower Unit of classification serial connection

Technical field

The utility model relates to a kind of Hydropower Plant, particularly relates to a kind of Hydropower Unit of classification serial connection.

Background technique

Worldwide, the electric power that the water power plant provided accounts for 24% of whole world electricity consumption, and it provides the energy for the people above 1,000,000,000.According to the data that American National renewable energy sources laboratory provides, water power plant in the world adds up to the electric energy of output 675,000 megawatts, and this is equivalent to the energy of 3,600,000,000 barrels of crude oil.But present hydropower generator group can not be connected in series mutually, and waterpower can not be made full use of.

Summary of the invention

The purpose of this utility model just provides a kind of Hydropower Unit of classification serial connection, can make full use of waterpower resourses, and simple in structure, convenient and fast connection, cost and installation cost are lower, can being convenient to use of different environment.

For achieving the above object, the utility model adopts following technological scheme:

A kind of Hydropower Unit of classification serial connection, comprise water turbine, housing, generator, the water flowing housing of the impact water wheels of described generator set is in a pipeline or the pipeline water wheels cavity to be set, the pipe two ends are provided with adpting flange, water wheels be provided with in the pipeline or the water wheels cavity in, the waterexit end of water wheels cavity directly is communicated with or the curved surface smooth connection with outlet conduit, and generator set can be connected in series mutually or be connected with the classification power station dam body in river course separately.

Under the described generator frame is set, frame is connected with tube shell, and frame is the steel structure frame, and generator is threaded with frame or welds.

The beneficial effects of the utility model: because the water flowing housing of the impact water wheels of generator set is set to a pipeline, processing, easier for installation, and be convenient to maintenance, and because pipe ends is provided with flange, serial connection or convenient and fast connection with the dam building; Because generator set can be connected in series, when water by previous stage water turbine pipeline, the potential energy of its water still can play a role at next stage, has utilized waterpower resourses more fully; Simple in structure, cost is low, installation, easy construction.

Embodiment

With reference to Fig. 1, the utility model comprises as can be seen: water turbine 2, housing 8, generator 4, the water flowing housing 8 of the impact water wheels 2 of described generator set 1 is a pipeline 7, the pipe two ends are provided with

adpting flange

9,6, the intake pipe 7 and the outlet pipe 11 curved surface smooth connections of water wheels cavity 10, described curved surface smooth connection, the feed-water end and outlet pipe 11 joints that refer to the water wheels cavity are curved surface 12, level and smooth curved surface is connected with and is beneficial to the resistance that reduces water, make current smooth and easy, and the next stage generator set that is beneficial in the serial connection obtain more water energy.Generator is connected by axle 3 with water turbine, and frame 5 is set under the described generator, and frame is connected with tube shell 8, and frame is the steel structure frame, and generator is threaded with frame, is convenient to installing/dismounting like this, the transportation of being more convenient for.

With reference to Fig. 2, the utility model can be connected in series mutually as can be seen, the joint is provided with sealing material, can easily connect by screw, this serial connection generator set makes can accomplish between every grade of generator set that distance is nearer, this in some water conservancy environment, more favourable utilization with waterpower resourses, and other present generator set are difficult to accomplish this point.

With reference to Fig. 3, the utility model also can be connected in series with river course 10 on the river course as can be seen, only need on the river course, to repair a check dam 11, just can be connected with generator set easily, thereby it is very convenient to construct, as middle-size and small-size power station, as long as Hydropower Unit possesses erosion and the safety installations of avoiding wind and rain, do not need other complicated building just can play a role, thereby investment is little.

With reference to Fig. 4, Fig. 5, Fig. 6, be another mode of execution of the present utility model, as can be seen from the figure the intake pipe of water turbine directly is communicated with outlet pipe, described direct connection is meant that the intake pipe of water turbine and water turbine outlet pipe are coaxial straight line, so more help the utilization of water potential energy, improve the efficient of packet concatenation generating.
